Coming up to my 1 yr anniversary since purchasing the K-JC704 machine and it’s been nothing but great! Customer service has been amazing since the start and very helpful when things pop up!
Cody and his team have been so helpful to us. We didn’t know much about crushers going into this new venture but Komplet has been behind us every step of the way. They’ve offered great support and were on hand every time we needed them with prompt and courteous service. Through the pandemic and supply chain problems they came through for us with great parts availability as well. I’m very grateful to have them behind us.
I have a Komplet 5030 screener and a Komplet 7040 mobile crusher that I purchased as demo units. The 5030 scalper type screener allows me to screen soils as well as aggregates. The 7040 allows me to add recycled concrete to my list of services that I have by going green and recycling busted slabs instead of burying at a landfill. These machines have been reliable and the parts and support that I receive from the distributor has been very good. Being able to diversify and add services in unstable times is key to being successful and having a good supporting distributor is a must.
Cody and Joe have been great since day one in our search for a crusher that met our needs. They are always available to answer any questions and help us with any of our needs during the purchase process and after the sale as well. We were looking for a crusher that was portable enough for us to move on our own and be able to crush concrete from our disposal and demolition waste business with an output material that was useable without adding a screener. It has done exactly what we wanted it to do by keeping the concrete waste out of the landfill which saves us money and now it’s putting money back into our pockets by selling the aggregate.
I purchased my Komplet jaw crusher 2 years ago. Recycling concrete and crushing rock has helped cut down on my import and export costs. I have had very few problems with my crusher. Cody and the entire Komplet team has been terrific with parts and any questions I have. I would highly recommend Komplet products.
I purchased this compact crusher in hopes to use it on many small concrete removal jobs and to aid in the services I provide. It has been a huge asset to be able to recycle concrete both on job sites and at the yard. While local concrete recycling facilities have grown highly restrictive on the products they accept, having a portable unit allows me to worry a lot less on what material I am able to remove from jobsites and stretch my productive hours past the time those dumpsites close. As for sales and product support, the team has been very helpful anytime I have had any issues and would recommend them for anyone looking for equipment.
While I haven’t contacted Komplet since the one time I had to service a machine, the one experience I had can speak for itself. The tech support was absolutely on point. I was able to get what I needed and very fast. If I remember correctly (it’s been a couple of years) I was contacted shortly after the initial call to them to make sure I was taken care of.
We are primarily using the LT4825 to crush waste concrete into crush for putting on the city streets and alleys that are gravel. It is a good machine. We probably could have went bigger but this unit fit into our price range better.
Great company to deal with Cody is on his A game with customer service always a pleasure to do business with. Thank you guys.
Purchased SC221 screener to helps us produce usable products from our small rock crusher. The SC221 keeps up great with our crusher to produce 2 sizes of gravel and Item #4 base material. Amazing machine. Sales staff was great, service was responsive and helpful.
We got one of the small jaw crushers for a large building that we were demolishing it was all block and brick we ran this machine steady for about a month, and we were so surprised by the pile of stone we were able to save and use for a parking lot it saved us dump fees and we were able to save on buying material for the stone parking lot. My only regrets are that we did not get the larger machine to take on larger projects. I would buy a larger machine next time. This has been a hassle-free crusher.

How much material can the K-JC 704 crush per hour?
This unit will crush up to 90 tons per hour, however your output production will depend on specific material types, material sizes, desired output sizes, and the overall setup and operation of the machine.
Many variables can affect the actual production rate, including:
Material Type: Different materials have different densities and properties, which can impact processing efficiency.
Material Size: The size of the input material can affect the machine’s performance. Larger pieces may require more time to process.
Desired Output Size: The finer the output size, the longer it can take to process the material.
Operation Setup: Proper setup and maintenance of the machine are crucial for achieving optimal performance.
What does “up to tons per hour” really mean?
The “up to” production rating refers to the maximum potential output a machine can achieve under ideal conditions—this includes consistent feed material (size, hardness, and moisture), skilled operator use, proper setup, and minimal downtime. For example, clean concrete with no rebar, fed at a steady rate in optimal weather, will produce higher output than mixed, wet, or irregular materials. Every job site is different, which is why we emphasize that this is not a guaranteed or average output, but a best-case scenario metric. If you’re unsure what output to expect for your application, we’re always happy to review your material and help you model realistic results.
What size can the K-JC 704 crush down to?
This compact mobile crusher can crush material that is up to 16″ x 12″, down to a range of sizes from 3/4″ to 3-1/4″. Your output size can be hydraulically adjusted using the remote controller to any size within this range.
What type and size of materials can the K-JC704 process?
This compact mobile crusher works best with hard, brittle materials like concrete, limestone, sandstone, granite, asphalt, and other natural rocks. The jaw inlet opening is 27″ x 16″ so we recommend pre-processing material down to 16″ minus.
